One of the things I love about programs like Ableton and Cubase is the ability to customize the interface and make it an appealing and comfortable work place. I mean, Bitwig looks nice as is, but there are some things I wish I could change. A lot of my creativity is driven by what I see, what my environment is like, sounds I hear, etc. I know this isn't something that is of much importance, but it would be a nice feature. More track colors would be nice too. I'm sure I'm not the only one interested in this.

The devs are in the middle of much more difficult task of porting the rendering of the GUI from CPU to GPU and once it's done I'm certain skins / colours will get higher priority. Doesn't make much sense to add this now & then to re-add this for new rendering path.
